The ALE Module persistently stores IDoc objects and Transaction IDs (TIDs) for every transaction it receives from the SAP application. In releases of the connector prior to version 4.8.x, the connector used IBM WebSphere collaborations, business objects, and maps to store the data in the repository. Version 4.8.x of the connector replaces the previous way of TID management with the use of WebSphere MQ queues.
Attention: To enable the ALE Module to process IDocs to and from the SAP application, you must upgrade the connector. However, it is imperative that you allow the current IDoc processing cycle to complete before upgrading the connector.
Before you upgrade the connector to enable the ALE Module to process IDocs, you must complete the processing of current files in the event and WIP directories. Also, check the archive directory for failed and unsubscribed events.
To complete the processing of current files in the event and WIP directories:
UNIX |
---|
$CROSSWORLDS/connectors/SAP/ale/events $CROSSWORLDS/connectors/SAP/ale/wip |
Windows |
---|
%CROSSWORLDS%\connectors\SAP\ale\events %CROSSWORLDS%\connectors\SAP\ale\wip |
To complete processing of any failed and unsubscribed events:
UNIX |
---|
$CROSSWORLDS/connectors/SAP/ale/archive |
Windows |
---|
%CROSSWORLDS%\connectors\SAP\ale\archive |
Once these directories are clear, apply the upgrade and follow the configuration instructions in:
